Year-round analysis of long-term temperature, precipitation, and atmospheric patterns based on 1991 to 2020 data.
The climate profile provides a twelve-month overview of temperature, precipitation, humidity, wind, and daylight measurements for the Jacques Cousteau National Estuarine Research Reserve. These figures represent long-term averages for a single representative coordinate at an elevation of 10.6 meters. Data reflects standardized climatology metrics and does not account for localized variance or daily weather fluctuations.
Long term monthly temperature means, average minimum and maximum values, and daily precipitation rates across twelve months.
Analyze average temperature bounds, daily precipitation rates, humidity, wind speed, and calculated daylight across the calendar year.

See two months side by side and how much they differ. Both use the same 1991–2020 climate normals and NASA POWER data point as the table above, so they show typical conditions, not a forecast.
